I don’t know a link that clarifies that.
Last roadmap written about eevee does not dive into detail of each shader node.
https://en.blender.org/index.php/Dev:2.8/Source/Viewport/Eevee/Roadmap-SeptDec-2017
What is certain is that job was done for shader nodes.
Unsupported shader nodes (like hair,toon… ) were excluded from add menu.
Obviously, many inputs are not working with EEVEE.
Vertex color is a supported attribute. But I think that no other attribute is supported.
Particle info is not working at all. But Geometry is partially supported (pointiness is not).
Fresnel is working, Wireframe is not.
That is WIP status.
Currently clément is working on a lightcache branch.
There will probably be a clarification at release of 2.80. But actually, they are acting.
